It's the second four-way poll posted to RealClearPolitics that
showed Clinton with 50% support.

The other was in early August, when Trump experienced a nearly
identical collapse in the poll following a series of
controversies. That poll was also conducted by Monmouth.

In Monday's poll, Clinton was ahead of Trump 50% to 38% among
likely voters.

"Clinton has increased her lead among all registered voters, but
the main difference between this month and last month is that her
supporters have become more enthusiastic, and thus more likely to
turn out while Trump backers have become less likely to vote,"
said Patrick Murray, director of the independent Monmouth
University Polling Institute.

Trump's polling numbers deteriorated following the
release of a tape from 2005 earlier this month in which Trump
boasted about groping women and kissing them regardless of their
consent.

Following the release of the tape, a score of women accused Trump
of making unwanted sexual advances in the past.
